ACORPORATION OF INDIANA UISEDVJOURNAL Box ant nna-- Application ,fileafmgfis;

This' invention relates to the art of loosening rolls of waste which have been use din the packlng of journal boxes of locomotives,

vehicles. V r 1 Waste taken from 1ournal boxes". 1s now freight cars, passenger cars, and other like commonly washed out in hot oil and during 1 such Washing. operations the'waste is preferably pulled apart slightly and opened upto permit foreign matter-such as sand, Babbitt metal, carbon and the' like to be separated from the waste.- It is a'common practice-to packjournal boxes of the type above inclicated with a roll of waste'a'round the back part of the box. This roll is originally formed from new waste and is wrappedabout a rapidly revolving spindle and has twine wrapped around the roll thus formed to hold it in shape. When the journal boxes are cleaned out and the old waste removed there from, these packing rolls of'course are taken out with the other loose Waste and upon the possible. I 7

Another important object of the invention waste containing such rolls'being dumped into awashing machine it has been practically impossibleto open up these rolls within the Washing machine and clean the Waste therein.

It is the primary purpose ofthls inventlon to provide, means for opening or loosening such packing rolls of Waste prior to the roll in such a manner that the fibers of the waste are not cut more than is necessary so-as to prevent the forming of short ends as much as is to provide mechanical means for so open} ing the packing rolls whereby the operation. may be quickly performed with the minimu nexpenditure of time and labor.

These and other objects will become apparent in the following description of the accompanying 'Ldire'ctionfand the othen-rollerin-the opposite 4 or 'counter cloekwis'e directionso: that the relativetravel betweenlthe rollers is down- ;iWardl y.,:.: I gr, l

In order to prevent having to make the entire roller 11 out of material suitable to'maintain a cutting edge',-the roller 11 is builtup in section, Fig. a, to have the knife 18 gripped-between t'he sections 19' and 20 thereofby means of the] through bolts '21; The bottoms of the grooves'oneitherside of the knife 18 are-also j preferably icorrugated transversely in order to present a roughened-surface Below-the rollersll and 12 supported by I the J frame '10 'we mount the drive shaft 22 whichis conneci zecl by the gear 23 with-the parallel-j counter shaft 24; The shaft 22 is driven; through the chain 25 and from each of the shafts 22 and 24 drive chains extend to sprocket wheelson-the shaft laof the roller 12 and the shaft 26:.of the roller 11 whereby "one roller is driven in a clockwise We mount a hopper. 27 immediately above the rollersi'tohave its lower end discharging to between: the rollers. Inop'erating the structure above describeda packing roll '28 here shown as having the twine 29 wrappedtherearound is dropped into the-hopper27 which is so shaped as to direct: the roll 28 by one end thereof centrally to between 'the rollers 11 and 12. Upon the'roll 28 comingin contact with the rollers, it is drawn therebetween and compressed over the ring 17 which causes the twine 29 about the roll to be placed under considerable tension as the knife 18 revolves across the twine during the travel of the roll 28 downwardly between the rollers.

' The roller 12 is suitably "adjusted in relafcut-open side. w I 1 The packing roll thus out comes v on-out tion to the roller 11 to have the proper distance therebetween whereby the packingroll 28 is compressed around and pulled back over the ringl? sufliciently to supply the necessary tension on the twine-E29v but not permit- ;ting the knife 18 to cut down into the roll a lsufli'ci ent distance to cut the fibers of the waste itself to'any great extent. 'S-inceithe twine 29 is thus presented to the knife under considerable tension, slight contact withrthe knife is sufficient to permit the knife to out through thetwine which then springs. 1aterally away from the knife and releases the tension about the packing'roll and allows the waste to be extruded somewhat on the atherefore,;do not desireto be limited to that ing roll, a revolvable roller havingapair of precise form nor: any more thanmay be re quired'by the following claims.

We claim:

1. For opening a journal box waste packing roll, a roller, a central ring therearound, said roller having a groove at each slde of the ring, means for pressing the rollover said ring, and a knife presented-toward said ring over said roll adapted to engage theroll when pressedover said'ring.

2. For open ng a ournal box waste pack- -therearound and a circular knife separating said second roller grooves having its edge presented toward said first roller ring, and means for revolving said rollers in opposite directions. r

4. V F or opening a journal box waste packing IOllfiL revolvable roller having a pair of grooves therearound with a ring separating the grooves, a second revolv-able roller adjacent the first roller having a pair of grooves therearoun-d, and a circular knife separating said second roller grooves having its edge presented toward said first roller ring, the width and depth of said grooves in said rollers being sufiicient to permit said ro ll to be pressed over saidring and to project into said grooves. 7 i o 5. For openinga used ournal box waste packing roll having a confining twine thereabout, a ridge, means for flexing the roll laterally over the ridge to draw the twine taut across the upper side of the roll above said ridge, a knife having a cutting edge presented toward said ridge, and means for relative- 1y moving the roll past the knife to cause the knife'to contact with and cut the twine while taut. H o v I g I 6. Theniethod of releasing waste from a used journal box packing roll having confining twine wrappedtherearound which embodies. those stepsof flexing'the roll laterally 'of its length to present an outer taut side and of cutting through the twine on that taut side. I r f r 7. Themethod of releasing waste from a used journal box packing roll having confining twine wrapped therearound which comprises compressing the roll centrally along its lengthto pull the twine taut across a side thereof and have a central compressed section of waste thereunder with the waste relatively loose to either side thereof, and cutting the twine on the taut side;
